| titleOfInvention | A kind of rock sand making method based on building wall recovery |
| abstract | The invention discloses a rock-sand-making method based on building wall recovery in the technical field of building materials. The rock-sand-making method based on building wall recovery comprises the following steps: crushing a whole building wall by a hammer crusher The large pieces of steel in the building wall are taken out, put into the stone crusher to crush the rock, the crushed rock is screened through the screen, and the screened rock is put into the mixing bucket for stirring. An electromagnet is installed, and the metal debris in the screened rock is adsorbed by the electromagnet, and the rock that has removed the metal debris is put into the grinding machine for grinding and refining, and the ground rock is screened through the screen. After that, the remaining large-grained rocks are put into the grinding machine again for grinding and refining, and the sand making is completed. The present invention selects the recycled building walls for sand making, which reduces the utilization of resources, improves the utilization rate of resources, and effectively protects the environment. . |
